3 Algebra Problems: Simplifying

Subject: Solving Algebra Problems

I'm stuck on these problems.

  1) 35x+8-34x = 3-2

  2) -12a-7+4a = 37-12

  3) 10m+3-7m = 18+9

Please help me!

1) 35x + 8 - 34x = 3 - 2

   Simplify the left and the right sides:  1x + 8 =  1

   Subtract 8 from both sides and you get:     1x = -7

       Divide both sides by 1 and you get:      x = -7


2) -12a - 7 + 4a = 37 - 12

   Simplify both sides:      -8a - 7 = 25

   Add seven to both sides:      -8a = 32

   Divide both sides by -8         a = -4


3) 10m + 3 - 7m = 18 + 9

   Simplify both sides:  3m + 3 = 27
                             3m = 24
                              m =  8

I hope this helps clear things up.
